Php 图像-上载没有响应，无法访问$\u文件

这是我的文件上传脚本，我得到以下错误

Notice: Undefined index: fupload in C:\Users\Tuskar\Desktop\Projekt\htdocs\Project IT-Space\Profile\edit_profile_parse.php on line 8

但是根据应该没有错误，因为我确定了索引。似乎我没有访问$\u FILES数组的权限，因为在我遇到这个错误之前，我一直遇到其他类似的错误，或者程序完全通过if并直接转到else（未选择文件）

我知道这个脚本很原始，几乎不包含任何安全性，但我只想在添加其他功能（如最大文件大小或文件限制）之前，先让它工作…：(

这是我正在使用的代码

Upload Picture
<form action="edit_profile_parse.php" method="get" enctype="multipart/form-data" >
<input type="hidden" name="MAX_FILE_SIZE" value="999999999"> </input>
<input type="file" name="fupload"> </input>
<input type="submit" name="submit" value="Upload"> </input>
</form>

上传图片

下面是处理表单的php

if (isset( $_GET['submit'] ))
{
if (isset($_FILES['fupload'] ))
{
echo "name: ".$_FILES['fupload']['name']." <br> ";
echo "size: ".$_FILES['fupload']['sizw']." <br> ";
echo "type: ".$_FILES['fupload']['type']." <br> ";

    if ($_FILES['fupload']['type'] == "image/gif")
    {
        $source = $_FILES['fupload']['tmp_name'];
        $target = "images/" .$_FILES['fupload']['name'];
        move_uploaded_file($source, $target) or die ("Error: " .mysql_error());
        $size = getImageSize($target);

        $imgstr = "<img src=\" '".$target."' \">";
        echo $imgstr;
    }
    else
    {
    echo "Problem uploading the file ... ";
    }
}   
else
{
echo "No file chosen !! ";
}
}
else
{
echo "Button not clicked ";
}

if（isset（$\u GET['submit']））
{
如果（isset（$\u文件['fupload']））
{
echo“name:”.$\u文件['fupload']['name'].“
”；
回显“大小：”.$\u文件['fupload']['sizzw'].“
”；
echo“type:”.$\u文件['fupload']['type'].“
”；
如果（$_文件['fupload']['type']==“image/gif”）
{
$source=$\u文件['fupload']['tmp\u名称']；
$target=“images/”$\u文件['fupload']['name']；
移动上传的文件（$source，$target）或死亡（“错误：.mysql\u Error（））；
$size=getImageSize（$target）；
$imgstr=“”；
echo$imgstr；
}
其他的
{
echo“上传文件时出现问题…”；
}
}   
其他的
{
回显“未选择文件！！”；
}
}
其他的
{
回显“按钮未点击”；
}

您应该使用表单方法发布而不是获取

<form action="edit_profile_parse.php" method="post" enctype="multipart/form-data" >

确保表单标记具有method=“POST”。GET请求不支持多部分/表单数据上载。
